Quick, Easy Keto Breakfast Casserole Recipe by JUSTIN WINN


When following a low-carb diet, it’s nice to have easy breakfast options on hand. This sausage breakfast casserole is a go-to for an easy Keto breakfast. Just make it over the weekend and you can easily reheat the leftovers for an easy breakfast!


Eating a keto/low carb diet is hard, and we’ve found it can feel pretty limiting in what vegetables you consume. Sometimes you really want the flavor of garlic and onions, you know?

The good news is, when you make a large dish like this keto breakfast casserole, per serving you are only getting a small amount of garlic and onion so it remains fairly low carb. We also added in some mushrooms, spinach, and fresh sage to compliment the eggs and sausage.


Cheese is really amazing, but we like providing you with options. Not everyone can tolerate dairy or might be cutting out dairy for a Whole30 or other reasons. For this recipe, the cheese is totally optional. It will turn out great either way! We added some avocado on top when we left out the cheese for a little bit of extra flavor.


Go ahead and whip up this low-carb breakfast casserole for a family brunch or to have leftovers to eat for the week. Leave a comment below to let us know how it goes.
